Have you ever looked at your GitHub history? What does it say about your career?
The fact that nobody reads the posts I publish here in no way dissuades me from publishing more.
Guardrails made easy:

“use no hallucination”
Input raw contracts, reports, and research papers to your agents, and use Docling to turn it into structured data.

Try it out yourself, directly from Claude Desktop or via the MCP server or Python SDK.
github.com/docling-proj...
GitHub - docling-project/docling: Get your documents ready for gen AI
Get your documents ready for gen AI. Contribute to docling-project/docling development by creating an account on GitHub.
github.com
That’s what Docling does:
📄 Converts PDFs, Word, and HTML into clean Markdown or structured JSON.
⚡️ Runs as an MCP server so agents can parse documents in real time.
🔓 100% open-source, and already ⭐️ 42K+ GitHub stars.
AI can finally read all your documents.

Not just parse text but actually understand structure, sections, and tables.
Evaluation of your AI app (or agent) is like testing your “regular” application. Very much needed but often overlooked
The very moment it became clear Europe is ngmi
“𝗩𝗶𝗯𝗲 𝗰𝗼𝗱𝗶𝗻𝗴 𝗶𝘀 𝗳𝗮𝘀𝘁. 𝗦𝗰𝗮𝗹𝗶𝗻𝗴 𝗶𝘀 𝗵𝗮𝗿𝗱.”
Everyone says they want to “vibe code,” until it actually looks like this 👇

🧾 Endless design docs
🧪 Weeks of test writing
💾 Legacy tech for “stability”
🔍 4 rounds of code reviews
🧤 Manual QA on every pixel

Sometimes the best way to move fast… is to just build.
never disrupt your coding agent mid session
anyone remember this trend?
vibe coding a calculator app
Weekends are for having fun with AI, recorded some of my vibe coding to share soonish
Building evergreen app with AI is cute

What I like to see is “build X using my companies’ design system, connecting to our internal microservices and deployed on this AWS cluster”
People ask: “can AI write full stack apps yet?”

My take: yes, but the challenge is in stitching components, handling edge cases, connecting to non-evergreen infra

Bullish it won’t take long to get there
peak developer performance

locked in for the rest of the year
wait until you see my ./node_modules
MCP just turned Chrome DevTools into an AI tool.

From your IDE you can now directly debug and inspect your web applications using MCP

(great demo by the Chrome DevTools team)
If I'm excited about one thing, it is being a developer

With AI I'm able to write code much faster and efficiently
People that had no skills before AI, will still have zero skills with AI
"You cannot scale without Kubernetes"

Says the corporate dev who has never shipped a feature in hours
I'm locked in until the year ends

All work, family and playing around with AI tools
If you really believe MCP does not matter you have never built any serious agentic tools
Why did OpenAI go with GPT-4 for DevDay instead of their newest models?

Curious what went on behind the scenes there.
